This expert-level guide details a test of Speer 147gr Gold Dot 9mm ammunition fired from a CZ Scorpion. The analysis focuses on whether the load remains subsonic and its terminal ballistics, utilizing ballistic gel and high-speed imaging. The test reveals the ammunition's performance characteristics, including penetration, expansion, and velocity from the specific firearm platform.

Quick Summary

Testing Speer 147gr Gold Dot 9mm from a CZ Scorpion revealed an average velocity of 1,160 FPS, slightly supersonic. Terminal ballistics were strong, with 16.4"-17.0" penetration and ~0.57" expansion in bare gel, and 19.4"-20.5" penetration with ~0.65" expansion through heavy clothing, confirming its defensive effectiveness.

Frequently Asked Questions

Will 147gr 9mm Speer Gold Dot stay subsonic from a CZ Scorpion?

From a CZ Scorpion with a 7.72-inch barrel, the Speer 147gr Gold Dot 9mm averaged 1,160 FPS. This velocity is slightly supersonic, exceeding the typical subsonic threshold of 1125-1150 FPS, but remains close to it.

What is the terminal performance of Speer 147gr Gold Dot 9mm from a CZ Scorpion?

The Speer 147gr Gold Dot 9mm showed robust terminal performance, achieving 16.4"-17.0" penetration and ~0.57" expansion in bare gel, and 19.4"-20.5" penetration with ~0.65" expansion through heavy clothing.

Is 147gr 9mm Gold Dot a good defensive round from a CZ Scorpion?

Yes, despite being slightly supersonic from the CZ Scorpion, the 147gr Gold Dot demonstrated excellent weight retention and consistent expansion, indicating it is a suitable and effective choice for self-defense.

How does barrel length affect 9mm subsonic ammunition?

Barrel length significantly impacts velocity. A longer barrel, like the 7.72-inch one on the CZ Scorpion tested, can increase the velocity of 9mm ammunition, potentially pushing loads that might be subsonic in shorter barrels into supersonic speeds.
